Interesting article. I had no idea that the Cherokee were originally from western North Carolina. It would be cool if there was a map that showed the native areas that tribes have lived. (There is one floating around the internet but it turns out it's an "artist interpretation" rather then a scientific map)

I am guessing he meant how Cherokee forms nouns by chaining verbs and adjectives or whatever. But I have no idea how D'ni actually works. The D'ni language could be thought of as a "math equation" in the sense that D'ni letters and numerals are related to one another.

The "equations" of D'ni are fairly trivial: prefixes and suffixes are easy to distinguish and identify and there's a clear distinction between nouns and verbs, while in Iroquoian languages (such as Cherokee), prefixes and suffixes can take different forms depending on context, it's not always easy to tell one from another, and as the article mentions, many "verb" roots can be used to refer to entities rather than actions.
